How loud is the freeze dryer pump? The pump operates at about 65-75 decibels, similar to a normal conversation or dishwasher. Many customers place their freeze dryer in a garage or separate room for quieter operation.
Let's do a simple math exercise. Non Frozen food put in freeze dryer at an ambient temp of 70F needs to be at -40F before the dry cycle begins. things go linear, each hour the temps would drop the food by 12.
I thought an easier way to see what was happening would be to make a time lapse video of an entire freeze drying cycle. As I was about to prepare some apples for freeze drying yesterday, I thought it would be a good time to do that -- so out came the GoPro.
5. Maintenance: Understand the maintenance requirements of the machine. Some units require more frequent servicing than others.
” As sponsored posts go, it was very accurate and not nearly as “salesy” as I’ve seen from other sponsored posts. I’ll share it below, but first I want to answer the question directly.
Freeze drying is a dehydration process that removes moisture from food while preserving its structure and nutritional value by freezing it first and then creating a vacuum around it.
I've also added an oil catch can that does a wonderful job of trapping oil vapor exiting the exhaust of the pump. Now instead of coating the area in a fine oil mist, the oil settles into the can. The clear tube on the side of the can lets you know how full the can is.
The pros and cons are easy to understand. In fact, there really is only one pro and it’s a huge one. YOU control the food you’re storing away for yourself and your family.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze cycle with pre-frozen food. I have my chest freezer set to -12F, and I usually let the freeze dryer cool for an hour before I put the frozen food in. After Buy Now I load the food in I wait another half hour to start the drying process. I've had a lot of cycles that the Completa time between pulling one batch out and starting the drying cycle on the next is around 2 hours. I'm running mine in a cold garage, so it cools down pretty quickly. If you have yours in a warm room it would probably take a little longer.
A funny lesson I learned is that we pelo longer freeze-dry many fruits or vegetables. I know this goes against what most preppers say but I’ve come to a different conclusion. We did tons of fruits get more info and vegetables at first but considering the time it takes we found that we are better served by spending that precious freeze drying usage on more expensive items like meats, eggs, and complete meals.
A description of the product, including details such as build quality, materials used and reasons to purchase.
The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Both pumps come with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for pelo oil spray at all and it will last much longer.
